MG-300 : MG 300 looks good on paper but.........................

OK After many glowing YouTube reviews for the NUX MG300 it appeared to be what I was after for home DAW recording. The factory presets must have been set up by a work experience kid as they are plain nasty, many sound like they are coming through a tunnel and the volume levels are all over the place???? I tried for many days to write some decent patches and whilst some were just OK there were these horrible constant un musical transients some around 1K and others around 3K? I already have the Moore Radar IR pedal and honestly it is far superior where it counts, 'the sound'. The MG300 is trying to be a one stop shop and in doing so it features a lot of very average IR's (that are basically unsatisfactory unless you're 16 and just starting out) & amps and effect units (and a drum machine, and a looper) On paper it seems too good to be true and of course it is.
